If you’ve been searching for how long does a bathroom renovation take, here’s the short answer. Most Melbourne bathroom renovations take between three and eight weeks, depending on the size of the bathroom, whether you’re changing the layout, and how old your home is. I’m Jake, and I’ve been building and renovating bathrooms across Melbourne for 15 years. This isn’t a guess pulled from an industry average. It’s what I see on real jobs, week in and week out.
A lot of homeowners come to me after reading conflicting timeframes online. One site says two weeks, another says three months. The truth sits somewhere in between, and it depends on a handful of things that are specific to your bathroom and your home. Let’s walk through exactly what shapes that timeline, stage by stage, so you know what to expect before you even pick up the phone.
What Actually Determines How Long Your Bathroom Renovation Will Take
Every bathroom renovation has its own rhythm, but a few factors show up again and again as the ones that speed a job up or slow it down.
- The size and layout of your bathroom. A small ensuite takes less time than a full family bathroom with a separate toilet.
- Whether you’re moving plumbing. Keeping your toilet, shower, and vanity where they already are is faster than relocating them.
- The age of your home. Older weatherboard and brick veneer homes, common across Melbourne’s inner east, often need extra prep work before tiling or waterproofing can begin.
- Product lead times. Custom vanities, imported tiles, and semi-frameless shower screens can take weeks to arrive, and that clock starts the day you order, not the day demolition finishes.
- Council permits and inspections. Some renovations need council sign-off, and in heritage overlay suburbs this can add extra steps for that specific property.
- Trade availability. Good plumbers, electricians, and waterproofers are in demand across Melbourne right now, so scheduling around them matters.
- Waterproofing sign-off. In Victoria, waterproofing often needs to be completed or signed off by someone appropriately licensed, and this step simply can’t be rushed.
Once you understand these variables, the week-by-week breakdown below will make a lot more sense.
The Bathroom Renovation Process, Stage by Stage
This is the sequence most Melbourne bathroom renovators follow. The order can shift slightly depending on your home, but the stages themselves rarely change.
Stage 1: Planning, Design, and Approvals (1 to 3 weeks)
This is where your builder visits the site, takes measurements, and confirms exactly what’s being done. It’s also when your HIA contract and Domestic Building Insurance paperwork get sorted, and when you should order any custom fixtures. If your renovation needs a council permit, this is when it gets lodged, and turnaround times vary by council. Ordering early here saves you real time later.
Stage 2: Strip Out and Demolition (2 to 5 days)
Old tiles, fixtures, and wall linings come out. If your home was built before the 1990s, this stage can take a little longer because materials need to be handled carefully in case they contain asbestos. It’s a safety step, not a shortcut anyone should skip.
Stage 3: Plumbing and Electrical Rough-In (2 to 5 days)
Your plumber and electrician move or upgrade the pipework and wiring behind the walls. If you’re keeping your toilet and shower in their current spots, this stage moves quickly. If you’re relocating them, expect a few extra days while the trades reroute everything properly.
Stage 4: Waterproofing (2 to 4 days, including cure time)
Waterproofing in Australia follows the AS 3740 standard, and it needs time to cure properly before tiling starts. I know this feels like the slowest part of the job when you can’t see much happening. But rushing waterproofing is how bathrooms end up with leaks and mould years down the track. It’s worth the wait, every time.
Stage 5: Tiling (5 to 10 days)
Floor and wall tiling happens here, followed by grouting and curing. Large format tiles or feature patterns take longer to lay properly, so if you’ve fallen in love with a herringbone floor, build in a few extra days.
Stage 6: Fixing, Fitout, and Final Touches (3 to 7 days)
Your vanity, toilet, tapware, and shower screen go in. Painting, mirrors, and accessories follow, then a final clean and walkthrough with your builder. This is the stage where your bathroom finally starts to feel real.

Realistic Timeframes by Renovation Type
Cosmetic Refresh: 2 to 3 weeks
New fixtures, tapware, and paint, without moving plumbing or changing the layout. These jobs run quickest, though product delivery times can still hold things up.
Full Bathroom Renovation: 4 to 6 weeks
A full strip-out and rebuild, keeping the existing layout. This is the most common project I take on across Melbourne, and it usually runs smoothly if fixtures are ordered early.
Full Renovation With Layout Changes or Structural Work: 6 to 10 weeks
Moving plumbing, changing the floor plan, or repairing structural issues found once walls are opened up. These jobs take longer because more trades are involved and more can be found along the way.
What Can Delay a Bathroom Renovation
Even a well-planned project can hit a snag. The most common causes I see are:
- Hidden issues behind walls or under floors, like old plumbing, timber rot, or subsidence, that only show up once demolition starts
- Product back orders, especially for imported tapware or custom joinery
- Waiting on council inspections at key stages of the build
- Weather delays if any part of the job involves external access
- Scope changes requested partway through the project
None of these is reasons to panic. They’re reasons to plan for a buffer, which we’ll cover shortly.
How Melbourne’s Older Homes and Heritage Property Can Affect Timing
Melbourne has a lot of beautiful older homes, particularly across the inner east. If your property sits within a heritage overlay, such as those managed by Boroondara Council, any renovation is assessed at a property-specific level, not as a blanket rule across the whole suburb. Your builder should check this for your exact address before work begins.
Weatherboard and period homes also tend to need extra care during structural and waterproofing work, simply because the original materials and building methods differ from modern homes. A short pre-renovation inspection can flag these details early, and the time it adds up front is almost always worth it.
Tips to Stop Your Bathroom Renovation Running Late
A few habits make a real difference to how smoothly your project runs:
- Confirm your fixtures and finishes before demolition starts, not during it
- Ask your builder for a written stage-by-stage schedule so you know what’s happening and when
- Choose a VBA licensed builder with a clear HIA contract, so responsibilities and timeframes are documented properly
- Build in a small buffer if your home is older or you’re renovating outside metro Melbourne
Frequently Asked Questions
What’s a Realistic Timeline for a Small Melbourne Bathroom?
A small bathroom or ensuite with no layout changes usually takes two to three weeks from start to finish.
Can I use my bathroom at all during a renovation?
Not usually, once demolition begins. If it’s your only bathroom, it’s worth arranging alternative access for the main renovation period.
Does waterproofing really need days to cure?
Yes. Waterproofing membranes need proper curing time before tiling starts, and skipping this step is one of the most common causes of future leaks.
Why do older Melbourne homes take longer to renovate?
Older homes can have outdated plumbing, different wall materials, or structural quirks that only become visible once the room is stripped back.
How far in advance should I order my bathroom fixtures?
The sooner the better, and locking them in during the planning stage gives you the most breathing room. Custom vanities and imported tapware can take several weeks to arrive.
